STM32F105RB microcontroller

The STM32F105xx device incorporates the high-performance ARM® Cortex™-M3 32-bit

RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash

memory up to 256 Kbytes and SRAM 64 Kbytes), and an extensive range of enhanced I/O

and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, four

general-purpose 16-bit timers plus a PWM timer, as well as standard and advanced

communication interfaces: up to two I2Cs, three SPIs, two I2Ss, five USARTs, an USB OTG

FS and two CANs.

The STM32F105xx operates in the -40 to +105 °C temperature range, from a 2.0 to 3.6 V

power supply. A comprehensive set of power-saving mode allows the design of low-power

applications.

The STM32F105xx offers devices in three different package types: from 64 pins to 100 pins.

Depending on the device chosen, different sets of peripherals are included.

These features make the STM32F105xx and STM32F107xx connectivity line

microcontroller family suitable for a wide range of applications such as motor drives and

application control, medical and handheld equipment, industrial applications, PLCs,

inverters, printers, and scanners, alarm systems, video intercom, HVAC and home audio

equipment.

Please refer to the STM32F105xx datasheet for an overview of the complete range of

peripherals proposed in this family.

Please refer to the STM32F105xx reference manual RM0008 to get more information on the

microcontroller operation.

The STM32F105RBT6 has a 64-pin LQFP package with 128 KBytes Flash memory and

operates in the -40 to +85 °C temperature range.
